So much fun!
- Create a folder.
- Place a copy of your game in the folder. I am using the shareware version of Commander Keen here.
- In that folder, create a file called
dockerfile, paste in the following code.
FROM ubuntu:22.04
ENV USER=root
ENV PASSWORD=password1
ENV DEBIAN_FRONTEND=noninteractive
ENV DEBCONF_NONINTERACTIVE_SEEN=true
COPY keen /dos/keen
RUN apt-get update && \
echo "tzdata tzdata/Areas select America" > ~/tx.txt && \
echo "tzdata tzdata/Zones/America select New York" >> ~/tx.txt && \
debconf-set-selections ~/tx.txt && \
apt-get install -y tightvncserver ratpoison dosbox novnc websockify && \
mkdir ~/.vnc/ && \
mkdir ~/.dosbox && \
echo $PASSWORD | vncpasswd -f > ~/.vnc/passwd && \
chmod 0600 ~/.vnc/passwd && \
echo "set border 0" > ~/.ratpoisonrc && \
echo "exec dosbox -conf ~/.dosbox/dosbox.conf -fullscreen -c 'MOUNT C: /dos' -c 'C:' -c 'cd keen' -c 'keen1'">> ~/.ratpoisonrc && \
export DOSCONF=$(dosbox -printconf) && \
cp $DOSCONF ~/.dosbox/dosbox.conf && \
sed -i 's/usescancodes=true/usescancodes=false/' ~/.dosbox/dosbox.conf && \
openssl req -x509 -nodes -newkey rsa:2048 -keyout ~/novnc.pem -out ~/novnc.pem -days 3650 -subj "/C=US/ST=NY/L=NY/O=NY/OU=NY/CN=NY [email protected]"
EXPOSE 80
CMD vncserver && websockify -D --web=/usr/share/novnc/ --cert=~/novnc.pem 80 localhost:5901 && tail -f /dev/null
- Build the image. I’m assuming you already have Docker installed and are familiar with it to some extent. CD to the directory in a console and run the command…
docker build -t mydosbox .
- Run the image.
docker run -p 6080:80 mydosbox
- Open a browser and point it to http://localhost:6080/vnc.html
- You should see a prompt for the password. Type it in, and you should be able to connect to your container with DosBox running.
- Once your image is built, you can push it to your image repository with docker push, but you’ll need to tag it appropriately.
